I love 'em! Felt even more decadent just now, cos of course now I've
got the TV hooked up to my new amp AND sexxy speakers. Listening to
TV through that lot?! A bit overkill! Sound quality of TV really is
naff!

Is that via analogue or DTV?.....

Derrm, well, it comes ultimately from my NTL set-top-box. Sometimes
I hear compression artefacts.

There's a hell of a lot of compression on the video as well. If I sit
near-ish to the TV, it's very apparent that the pic is divided up into
basically "boxes", near-squares, perhaps 1cm x 1cm. Especially, not
surprisingly, when the scene suddenly changes, or there's fast
movement.

A couple of times, while I've had this PC running, and it went to
check and receive email, it's ****ed up the picture and the TV pic
just stopped completely! Broke up and froze! Obviously there was a
bandwidth shortage and the PC was hogging it while downloading the
email! Not good!

Also, the colours/levels of shading show very apparent compression.
In, say, a sky, where the colour changes gently from, say, top to
bottom, you can see it's rendered as wide-ish bands of the same colour,
rather than a truly smooth progression.

Welcome to the wonderful world of digital broadcasting

Personally I wouldn't give cable TV house room, if you must have it get
it off either freeview or satellite. However ntl are useful for the
broadband though.

DTV is transmitted at 256 kilobits on the sound and on the old analogue
its 728 NICAM which is faster still!. However the digital pictures are
still very poor compared with good analogue signals. Odd really in that
the actual transmitters are fed with very high rate digital and then
coded to PAL, which still offers the better picture.

No doubt I'll have Dave Plowman along shortly to contradict all that!...
